Method: CGLM::AABB#crop_until

Defined in:
ext/cglm/rb_cglm_aabb.c

#crop_until(crop, clamp[, dest]) ⇒ Object

Crops this AABB by crop, placing the result in dest or creating a new one. Returns dest. If the result would be smaller than clamp, it is restricted to the extents of clamp instead.

This could be useful for gettng a bbox which fits with view frustum and object bounding boxes. In this case you crop view frustum box with objects box.
